Highly recommend this full exhaust, i can't say how difficult is to replace the OEM because i took the decision to be done at a proper motorbike garage, but what can i say is damnnnn sound incredible, i jumped a bit 😀 when the mechanic called me to hear how it's sounds, it's a clearly WOW. And for me, it looks fantastic, I've never been a fan of that big "bottle" slip on exhaust. Yeah, for whoever want to give it a try, i will say you'll never regret it!!!
